3 After 1 year After 2 years FV 1 = PV + INT 1 = PV + PV (I) = PV(1 + I) = $100(1.10) 10) = $ FV 2 =FV(1+I) 1 = PV(1 + I)(1+I) = PV(1+I) 2 = $100(1.10) 10) 2 = $ After 3 years FV 3 = FV 2 (1+I)=PV(1 + I) 2 (1+I) = PV(1+I) 3 = $100(1.10) 3 = $ In general, FV N = PV(1 + I) N Four Ways to Find FVs Step-by-step approach using time line (as shown in Slides 7-10). Solve the equation with a regular calculator (formula approach). Use a financial calculator. Use a spreadsheet

Set number of decimal places to display: Orange Shift key, then DISP key (in orange), then desired d decimal places (e.g., 3). To temporarily show all digits, hit Orange Shift key, then DISP, then =. HP10BII (Continued) To permanently show all digits, hit ORANGE shift, then DISP, then. (period key). Set decimal mode: Hit ORANGE shift, then./, key. Note: many non-us countries reverse the US use of decimals and commas when writing a number HP10BII: Set Time Value Parameters To set END (for cash flows occurring at the end of the year), hit ORANGE shift key, then BEG/END. To set 1 payment per period, hit 1, then ORANGE shift key, then P/YR. 15 Financial Calculator Solution Financial calculators solve this equation: FV +PV(1+I) N N =0 0. There are 4 variables. If 3 are known, the calculator will solve for the 4th. 16

5 Here s the setup to find FV INPUTS N I/YR PV PMT FV Clearing automatically sets everything to 0, but for safety enter PMT = 0. Set: P/YR = 1, END. Spreadsheet Solution Use the FV function: see spreadsheet in Ch04 Mini Case.xls = FV(I, N, PMT, PV) = FV(0.10, 3, 0, -100) = What s the PV of $100 due in 3 years if I/YR = 10%? Solve FV N = PV(1 + I ) N for PV Finding PVs is discounting, and it s the reverse of compounding. PV = FV N 1 = FV N (1+I) N 1+I N PV =? 10% PV = $ = $100(0.7513) = $

FV Annuity Formula 10% FV = The future value of an annuity with N periods and an interest rate of I can be found with the following formula: =PMT (1+I)N -1 I (1+0.10) 3-1 = $ = $331 32

9 Financial Calculator Formula for Annuities Financial Calculator Solution Financial calculators solve this equation: N -1 FV N + PV(1+I) N + PMT (1+I) I = 0 There are 5 variables. If 4 are known, the calculator will solve for the 5th. INPUTS N I/YR PV PMT FV Have payments but no lump sum PV, so enter0forpresentvalue Spreadsheet Solution Use the FV function: see spreadsheet. = FV(I, N, PMT, PV) = FV(0.10, 3, -100, 0) = What s the PV of this ordinary annuity? 10% = PV

10 PV Annuity Formula The present value of an annuity with N periods and an interest rate of I can be found with the following formula: =PMT 1 1 I I (1+I) N = $ = $ (1+0.1) 3 Financial Calculator Solution INPUTS N I/YR PV PMT FV Have payments but no lump sum FV, so enter0forfuturevalue future value Spreadsheet Solution Find the FV and PV if the annuity were an annuity due. Use the PV function = PV(I, N, PMT, FV) = PV(0.10, 3, 100, 0) = %

11 PV and FV of Annuity Due vs. Ordinary Annuity PV of annuity due: = (PV of ordinary annuity) (1+I) = ($248.69) ( ) = $ FV of annuity due: = (FV of ordinary annuity) (1+I) = ($331.00) ( ) = $ PV of Annuity Due: Switch from End to Begin BEGIN Mode INPUTS N I/YR PV PMT FV FV of Annuity Due: Switch from End to Begin BEGIN Mode INPUTS N I/YR PV PMT FV Excel Function for Annuities Due Change the formula to: =PV(0.10,3,-100,0,1) ) The fourth term, 0, tells the function there are no other cash flows. The fifth term tells the function that it is an annuity due. A similar function gives the future value of an annuity due: =FV(0.10,3,-100,0,1) 43 44

12 What is the PV of this uneven cash flow stream? % = PV Financial calculator: HP10BII Clear all: Orange Shift key, then C All key (in orange). Enter number, then hit the CFj key. Repeat for all cash flows, in order. To find NPV: Enter interest rate (I/YR). Then Orange Shift key, then NPV key (in orange). 46 Financial calculator: HP10BII (more) To see current cash flow in list, hit RCL CFj CFj To see previous CF, hit RCL CFj To see subsequent CF, hit RCL CFj + To see CF 0-9, hit RCL CFj 1 (to see CF 1). To see CF 10-14, 14, hit RCL CFj.

13 Excel Formula in cell A3: =NPV(10%,B2:E2) Nominal rate (I NOM ) 49 Stated in contracts, and quoted by banks and brokers. Not used in calculations or shown on time lines Periods per year (M) must be given. Examples: 8%; Quarterly 8%, Daily interest t (365 days) 50 Periodic rate (I PER ) I PER = I NOM /M, where M is number of compounding periods per year. M = 4 for quarterly, 12 for monthly, and 360 or 365 for daily compounding. Used in calculations, shown on time lines. Examples: The Impact of Compounding Will the FV of a lump sum be larger or smaller if we compound more often, holding the stated I% constant? Why? 8% quarterly: I PER = 8%/4 = 2%. 8% daily (365): I PER = 8%/365 = %

14 The Impact of Compounding (Answer) FV Formula with Different Compounding Periods LARGER! If compounding is more frequent than once a year--for example, semiannually, quarterly, or daily--interest is earned on interest more often. FVN = PV 1 + N I NOM M M N $100 at a 12% nominal rate with semiannual compounding for 5 years FVN = PV 1 + I NOM M 0.12 FV 5S = $ M N 2x5 = $100(1.06) 10 = $ FV of $100 at a 12% nominal rate for 5 years with different compounding FV(Ann.) = $100(1.12) 5 = $ FV(Semi.) = $100(1.06) 10 = $ FV(Quar.) = $100(1.03) 20 = $ FV(Mon.) = $100(1.01) 01) = $ FV(Daily) = $100(1+(0.12/365)) (5x365) = $

15 Effective Annual Rate (EAR = EFF%) The EAR is the annual rate that causes PV to grow to the same FV as under multi-period compounding. Effective Annual Rate Example Example: Invest $1 for one year at 12%, semiannual: FV = PV(1 + I NOM/ /M) M FV = $1 (1.06) 2 = $ EFF% = 12.36%, because $1 invested for one year at 12% semiannual compounding would grow to the same value as $1 invested for one year at 12.36% annual compounding Comparing Rates An investment with monthly payments is different from one with quarterly payments. Must put on EFF% basis to compare rates of return. Use EFF% only for comparisons. Banks say interest paid daily. Same as compounded daily. EFF% for a nominal rate of 12%, compounded semiannually I EFF% = 1 + NOM 1 M = M = (1.06) = = 12.36%

16 Finding EFF with HP10BII Type in nominal rate, then Orange Shift key, then NOM% key (in orange). Type in number of periods, then Orange Shift key, then P/YR key (in orange). To find effective rate, hit Orange Shift key, then EFF% key (in orange). EAR (or EFF%) for a Nominal Rate of of 12% EAR Annual = 12%. EAR Q = ( /4) 4-1 = 12.55%. EAR M = ( /12) 12-1 = 12.68%. EAR D(365) = ( /365) 365-1= 12.75% Can the effective rate ever be equal to the nominal rate? Yes, but only if annual compounding is used, i.e., if M = 1. If M > 1, EFF% will always be greater than the nominal rate. When is each rate used? I NOM : Witt Written into contracts, t quoted by banks and brokers. Not used in calculations or shown on time lines

17 When is each rate used? (Continued) I PER : Used in calculations, shown on time lines. If I NOM has annual compounding, then I PER = I NOM /1 = I NOM. When is each rate used? (Continued) EAR (or EFF%): Used to compare returns on investments with different payments per year. Used for calculations if and only if dealing with annuities where payments don t match interest compounding periods Amortization Construct an amortization schedule for a $1,000, 10% annual rate loan with 3 equal payments. Step 1: Find the required payments. 10% -1,000 PMT PMT PMT 67 INPUTS N I/Y PV PMT FV R

18 Step 2: Find interest charge for Year 1. INT t =Begbal t (I) INT 1 = $1,000(0.10) 10) = $100 Step 3: Find repayment of principal in Year 1. Repmt = PMT - INT = $ $100 = $ Step 4: Find ending balance after Year 1. Amortization Table End bal = Beg bal - Repmt = $1,000 - $ = $ BEG PRIN END YEAR BAL PMT INT PMT BAL 1 $1,000 $402 $100 $302 $ Repeat these steps for Years 2 and 3 to complete the amortization table TOT 1, ,

19 Interest declines because outstanding balance declines. $450 $400 $350 $300 $250 $200 $150 $100 $50 $0 PMT 1 PMT 2 PMT 3 Interest Principal Amortization tables are widely used--for home mortgages, auto loans, business loans, retirement plans, and more. They are very important! Financial calculators (and spreadsheets) are great for setting up amortization tables Fractional Time Periods On January 1 you deposit $100 in an account that pays a nominal interest rate of %, with daily compounding (365 days). How much will you have on October 1, or after 9 months (273 days)? (Days given.) Convert interest to daily rate I PER = %/365 = % per day % % -100 FV=? 75 76

20 Find FV Calculator Solution FV 273 = $100 ( ) 273 = $100 ( ) = $ I PER =I NOM/ /M = /365 = per day. INPUTS N I/YR PV PMT FV Non-matching rates and periods What s the value at the end of Year 3 of the following CF stream if the quoted interest rate is 10%, compounded semiannually? Time line for non-matching rates and periods mos mos. 5% periods

21 Non-matching rates and periods Payments occur annually, but compounding occurs each 6 months. So we can t use normal annuity valuation techniques. 1st Method: Compound Each CF % FVA 3 = $100(1.05) 4 + $100(1.05) 2 + $100 = $ nd Method: Treat as an annuity, use financial calculator Use EAR = 10.25% as the annual rate in calculator. Find the EFF% (EAR) for the quoted rate: EFF% = = 10.25% 2 INPUTS N I/YR PV PMT FV

22 What s the PV of this stream? 0 1 5% Comparing Investments You are offered a note that pays $1,000 in 15 months (or 456 days) for $850. You have $850 in a bank that pays a % nominal rate, with 365 daily compounding, which is a daily rate of % and an EAR of 7.0%. You plan to leave the money in the bank if you don t buy the note. The note is riskless. Should you buy it? 86 Daily time line Three solution methods I PER = % per day. 1. Greatest future wealth: FV 2. Greatest wealth today: PV 3. Highest rate of return: EFF% days ,

23 1. Greatest Future Wealth Find FV of $850 left in bank for 15 months and compare with note s FV = $1,000. FV Bank = $850( ) ) = $ in bank. Buy the note: $1,000 > $ Calculator Solution to FV I PER =I NOM /M = /365 = per day. INPUTS N I/YR PV PMT FV Greatest Present Wealth Financial Calculator Solution Find PV of note, and compare with its $850 cost: PV = $1,000/( ) ) = $ Buy the note: $ > $ INPUTS /365 = N I/YR PV PMT FV PV of note is greater than its $850 cost, so buy the note. Raises your wealth. 92

24 3. Rate of Return Calculator Solution Find the EFF% on note and compare with 7.0% bank pays, which is your opportunity cost of capital: FV N = PV(1 + I) N $1,000 = $850(1 + I) 456 Now we must solve for I. 93 INPUTS N I/YR PV PMT FV % 03 per day Convert % to decimal: Decimal = / /100 = EAR = EFF% = ( ) = 13.89%. 94 Using interest conversion P/YR =365 NOM% = (365) = EFF% =13.89 Since 13.89% > 7.0% opportunity cost, buy the note. 95
